ABSTRACT

A system for cloud acoustic enhancement is disclosed. In particular, the system may leverage metadata and cloud-computing network resources to mitigate the impact of noisy environments that may potentially interfere with user communications. In order to do so, the system may receive an audio stream including an audio signal associated with a user, and determine if the audio stream also includes an interference signal. The system may determine that the audio stream includes the interference signal if a portion of the audio stream correlates with metadata that identifies the interference signal. If the audio stream is determined to include the interference signal, the system may cancel the interference signal from the audio stream by utilizing the metadata and the cloud-computing network resources. Once the interference signal is cancelled, the system may transmit the audio stream including the audio signal associated with the user to an intended destination.

FIELD OF THE INVENTION

The present application relates to technologies for noise suppression, speech enhancement, and cloud-computing, and more particularly, to a system and method for providing cloud acoustic enhancement.

BACKGROUND

In today's society, end users regularly utilize smartphones, speech recognition systems, and other audio-based technologies to place and receive phone calls, access various types of internet services, and perform a variety of functions, or a combination thereof. When an end user communicates using such devices and technologies, the end user may be located in an environment that may not provide for optimal communication conditions. Such environments may include ambient noise, which may pose substantial challenges when end users attempt to communicate with others or with automatic speech recognition systems. In recent years, these challenges have only been exacerbated based on a number of trends. In particular, there has been a large migration away from traditional handset designs towards rectangular-shaped smartphones, which are inferior to traditional handset designs at coupling a talker's voice to the microphone of the smartphone. Additionally, an increasing number of end users are using speakerphones on both wired and wireless platforms, which admit substantial amounts of background noise relative to the talker's voice. Furthermore, there has been an increasing number of end users that are using smartphones in noisy environments, a greater societal acceptance of taking calls in the presence of others engaged in noisy activities, and an increasing use of automated speech recognition systems to interact with local and network resources.

In order to counteract the ambient noise existing in an end user's environment, traditional solutions typically involve brute-force processing, in isolation, of all of the various audio information occurring in the environment. Such brute-force processing often requires extensive use of limited network resources, causes communication delays, increases power usage, and increases network and other costs. While some currently existing solutions utilize noise suppression algorithms and technologies to separate a selected end user's audio signals from the ambient noise in the environment, such noise suppression algorithms and technologies often do so only by predefining the locations of the sources of the ambient noise and the location of the selected end user.

SUMMARY

A system and accompanying methods for providing cloud acoustic enhancement are disclosed. In particular, the system and methods may enhance a user's audio experiences by utilizing metadata associated with the user's desired audio stream, metadata associated with the user's environment, sensor data, and cloud-computing network resources to mitigate the impact of noisy conditions that may potentially interfere with the user's communications. In order to accomplish this, the system and methods may receive and analyze an audio stream including an audio signal associated with a particular user. As the audio stream is being received or at another selected time, the system and methods may determine, by utilizing a cloud-computing network, if the audio stream includes an interference signal that may potentially interfere with the user's communications. The system and methods may determine that the audio stream includes the interference signal if a portion of the audio stream is determined to correlate with metadata that identifies the interference signal.

If the audio stream is determined to include the interference signal, the system and methods may utilize various noise suppression algorithms and techniques to cancel or suppress the detected interference signal from the audio stream. In certain embodiments, the system and methods may utilize the metadata, noise profiles correlating with the interference signal, noise profiles associated with the user's environment and device, and the cloud-computing network to assist in the cancelling the interference signal from the audio stream. Once the effects of the interference signal are suppressed or cancelled from the audio stream, the system and methods may transmit the audio stream including the desired audio signal associated with the user to an intended destination. For example, the audio stream may be sent to a device of a caller communicating with the user, to an automatic speech recognition system that the user is using, to any other destination, or any combination thereof. Thus, the system and methods effectively leverage metadata and other information about the acoustic environment that the user is immersed in, along with cloud-computing resources, to dramatically improve end-to-end audio clarity and performance.

In one embodiment, a system for providing cloud acoustic enhancement is disclosed. The system may include a memory that stores instructions and a processor that executes the instructions to perform various operations of the system. Additionally, the system may perform any of the operations of the system by utilizing the resources of a cloud-computing network. The system may perform an operation that includes receiving an audio stream including an audio signal associated with a user. Once the audio stream is received, the system may perform an operation that includes determining if the audio stream includes an interference signal in addition to the audio signal associated with the user. The system may determine that the audio stream includes the interference signal if a portion of the audio stream correlates with metadata that identifies the interference signal. The system may then perform an operation that includes cancelling, if the audio stream is determined to include the interference signal, the interference signal from the audio stream. Notably, the interference signal may be cancelled from the audio stream by utilizing the metadata. After the interference signal is cancelled from the audio stream, the system may perform an operation that includes transmitting the audio stream including the audio signal associated with the user to an intended destination.

In another embodiment, a method for providing cloud acoustic enhancement is disclosed. The method may include utilizing a memory that stores instructions, and a processor that executes the instructions to perform the various functions of the method. Additionally, the method may be performed by utilizing the resources of a cloud-computing network. The method may include receiving an audio stream including an audio signal associated with a user. Additionally, the method may include determining if the audio stream includes an interference signal in addition to the audio signal associated with the user. The audio stream may be determined to include the interference signal if a portion of the audio stream correlates with metadata that identifies the interference signal. The method may also include cancelling the interference signal from the audio stream if the audio stream is determined to include the interference signal. The interference signal may be cancelled from the audio stream by utilizing the metadata. Furthermore, after cancelling the interference signal, the method may include transmitting the audio stream including the audio signal associated with the user to an intended destination.

According to yet another embodiment, a computer-readable device having instructions for providing cloud acoustic enhancement is provided. The computer instructions, which when loaded and executed by a processor, may cause the processor to perform operations including: receiving an audio stream including an audio signal associated with a user; determining if the audio stream includes an interference signal in addition to the audio signal associated with the user, wherein the audio stream is determined to include the interference signal if a portion of the audio stream correlates with metadata that identifies the interference signal; cancelling, if the audio stream is determined to include the interference signal, the interference signal from the audio stream, wherein the interference signal is cancelled from the audio stream by utilizing the metadata; and transmitting, after cancelling the interference signal, the audio stream including the audio signal associated with the user to an intended destination.

DETAILED DESCRIPTION OF THE INVENTION

A system 100 and accompanying methods for providing cloud acoustic enhancement are disclosed, as shown in FIGS. 1-8. In particular, the system 100 and methods may utilize cloud-computing network resources and metadata associated various environments, media content, noise sources, devices, users, and other sources to improve the speed and efficiency of noise suppression and cancellation algorithms used in enhancing various types of communications sessions. In order to accomplish this, the system 100 and methods may receive and analyze an audio stream including an audio signal associated with a particular user, such as first user 101. As the audio stream is being received or at another selected time, the system 100 and methods may determine, by utilizing a cloud-computing network, if the audio stream includes an interference signal that may potentially interfere with the user's communications. The system 100 and methods may determine that the audio stream includes the interference signal if a portion of the audio stream is determined to correlate with metadata that identifies the interference signal.

Notably, if the audio stream is determined to include the interference signal, the system 100 and methods may utilize various noise suppression algorithms and techniques to cancel the detected interference signal from the audio stream. In certain embodiments, the system 100 and methods may utilize the metadata, noise profiles correlating with the interference signal, noise profiles associated with the user's environment 108 and device, and the cloud-computing network to assist in the cancelling the interference signal from the audio stream. Once the effects of the interference signal are suppressed or cancelled from the audio stream, the system 100 and methods may transmit the audio stream including the desired audio signal associated with the user to an intended destination. As an example, the audio stream may be sent to second user device 111 of second user 110 who is communicating with the user, to an automatic speech recognition system 175 that the user is interacting with, to any other destination, or any combination thereof. Thus, the system 100 and methods utilize metadata and other information about the environment 108 that the user is immersed in, along with cloud-computing resources, to dramatically enhance end-to-end audio communications.

As shown in FIG. 1, a system 100 for providing cloud acoustic enhancement is disclosed.

The first user 101 and the second user 110 may utilize the first user device 102 and second user device 111, respectively, to engage in communications sessions and to access and obtain various types of content and services, such as, but not limited to, video content, audio content, web content, text content, automatic speech recognition services, and other speech-related services. Additionally, the first and second users 101, 110 may utilize the first and second user devices 102, 111 to perform a variety of other tasks and functions. In certain embodiments, the first user device 102 and second user device 111 may include a software application that may be an automatic speech recognition application, a cloud-based application, gaming application, an internet-based application, a browser application, a mobile application, a productivity application, a video application, a music application, a social media application, a financial application, a news application, any other type of application, or a combination thereof. In certain embodiments, the application may be utilized to provide de-noising services to the first and second users. In certain embodiments, at least a portion of the software application may be configured to execute directly on the first user device 102 and second user device 111, however, in other embodiments, the software application may be configured to execute on the other devices and components in the system 100.

The first user 101 of the first user device 102 may be located in an environment 108, which may be any type of environment, such as, but not limited to, a street, a stadium, an airport, a park, an office building, a vehicle, a body of water, a movie theater, or any other type of environment. In certain embodiments, the second user 110 may be located in the same environment 108 as the first user 101, however, in other embodiments, the second user 110 may be located in a different environment from the first user 101. In FIG. 1, the second user 110 is illustratively shown as not being located in the same environment 108 as the first user 101. The environment 108 may include ambient noise generated by one or more interferers, such as, but not limited to, interferer 114 and interferer 125. The interferers 114, 125 may be any type of object, person, or animal that may make noise in the environment 108 that may potentially interfere with communications made by the first user 101, the second user 110, or both. Illustratively, in FIG. 1, the interferer 114 is an interfering user that is using an interfering device 115, such as a smartphone, that includes a memory 116 that stores instructions and a processor 117 that executes the instructions to perform the various operations of the interfering device 115. Interferer 125 is illustratively shown in FIG. 1 as a vehicle. In certain embodiments, the environment 108 may also include noise generated by any other type of noise source as well.

The system 100 may also include a canceller 165, which may be utilized to cancel, or otherwise suppress, interference signals or other undesired audio signals so as to enhance communications made by the first user 101, the second user 110, or both.

In certain embodiments, the canceller 165 may be configured to store noise suppression, echo-cancellation, and other algorithms that enable the canceller 165 to cancel interference signals occurring in the system 100. In other embodiments, the canceller 165 may not store the noise suppression algorithms on the canceller 165 itself, but, instead, may access the algorithms from the database 155. The canceller 165 may receive audio streams including desired audio signals and undesired interference signals occurring in the system 100. Upon receiving such audio streams, the canceller 165 may utilize metadata, noise profiles, sensor data, and other information associated with the interference signals and the desired audio signals to suppress the undesired interference signals.

Additionally, the system 100 may include an automatic speech recognition system 175. The automatic speech recognition system 175 may be configured to receive audio inputs, such as, but not limited to, voice inputs, tone inputs, music inputs, or any other type of audio input. In certain embodiments, the automatic speech recognition system 175 may be configured to translate audio inputs into text, perform a variety of commands based on the audio inputs, or perform any other automatic speech recognition functions. The automatic speech recognition system 175 may reside within or outside the communications network 135, and may be communicatively linked with any of the devices in the system 100. In certain embodiments, the automatic speech recognition system 175 may be configured to receive audio streams directly from any of the devices in the system 100, however, in certain embodiments, the automatic speech recognition system 175 may be configured to only receive audio streams after they have been processed by the canceller 165 or by another device in the system 100 that may perform noise suppression services on the audio streams.

The functionality of the system 100 may be supported and executed by using any combination of the servers 140, 145, and 150 in the communications network 135 or outside of the communications network 135. In one embodiment, the server 140 may include a memory 141 that includes instructions, and a processor 142 that executes the instructions from the memory 141 to perform various operations that are performed by the server 140.

In one embodiment, the communications network 135 may be part of a single autonomous system that is located in a particular geographic region, or be part of multiple autonomous systems that span several geographic regions. The phone network 136 shown in FIG. 5 may be any type of phone network that may include, but is not limited to, a public switched telephone network, a VoIP network, any other type of phone network, or any combination thereof. In certain embodiments, that phone network 136 may be configured to reside within the communications network 135.

The database 155 of the system 100 may be utilized to store and relay information that traverses the system 100, cache content that traverses the system 100, store data about each of the devices in the system 100 and perform any other typical functions of a database. In one embodiment, the database 155 may be connected to or reside within the communications network 135, the phone network 136, or any combination thereof. Additionally, the database 155 may include a processor and memory or be connected to a processor and memory to perform the various operation associated with the database 155. In certain embodiments, the database 155 may be connected to servers 140, 145, and 150, server 160, first user device 102, second user device 111, the canceller 165, the automatic speech recognition system 175, the audio device 205, the broadcast device 305, the television device 405, the local noise source 605, or any combination thereof. The database 155 may also store the content and metadata obtained from the environment 108, store metadata associated with the first and second users 101, 110, store user profiles and audio profiles, store location information, store communications, store information about the interferers 114, 125, store noise profiles for the interferers 114, 125 and the interfering device 115, store user preferences, store noise cancellation and suppression algorithms, store metadata associated with the interference signals, store metadata associated with desired audio signals, store metadata associated with any device or signal in the system 100, store historical user usage pattern information, store any information traversing the system 100, or any combination thereof. Furthermore, the database 155 may be configured to process queries sent to it by any device in the system 100.

Similarly, the music database 157 may be connected to or reside within database 155. In certain embodiments, the music database 157 may store metadata identifying or otherwise associated with music content, noise cancellation algorithms and information for canceling interference signals containing such music content, user preferences associated with music content, store any information traversing the system 100, or any combination thereof.

Operatively, the system 100 may improve user communications through the use of cloud acoustic enhancement. In a first example scenario, as shown in FIG. 1, the first user 101 of the first user device 102 may be engaging in a communications session, such as a telephone call, with the second user 110 of the second user device 111. Additionally, the first user 101 may be engaged in a speech recognition session with the automatic speech recognition system 175. In this example, the environment 108 may be a busy street that includes ambient noise, such as noises made by interferers 114, 125, that may potentially interfere with the quality and perceptibility of the communications occurring during the communications session between the first and second users 101, 110 and during the speech recognition session between the first user 101 and the automatic speech recognition system 175. In order to counteract such interfering noises in the environment 108, the first user 101 may begin speaking through the first user device 102, and any detected audio inputs, including the speech, may be converted into an audio stream by the first user device 102. The audio stream may then be transmitted by the first user device 102 to the communications network 135 and ultimately to the canceller 165 for further processing.

Once the audio stream is received from the first user device 102, the system 100 may access metadata, noise profiles, user profiles, location profiles, and other data to assist in determining whether one or more interference signals exist in the audio stream. Additionally, the system 100 may harvest additional metadata and information associated with the first user 101, the first user device 102, the environment 108, the interferers 114, 125, the second user 110, or any of the other devices in the system 100 in real-time so as to supplement any previously existing metadata and profiles or to create new metadata and profiles. The harvested metadata may be predictive information that may assist in detecting and cancelling interference signals. The metadata may be harvested and extracted from visual content obtained from the camera 105, acceleration data captured by the accelerometer 106, orientation data captured using the gyroscope 109, location data captured by the global positioning sensor 107, data obtained by any of the devices in the system 100, or any combination thereof. The metadata may include, but is not limited to, information that indicates a location of the first user 101, information for identifying interference signals, information for cancelling interference signals through the use of noise suppression algorithms and echo-cancellation techniques, information that indicates what the interferers 114, 125 are, information that indicates the locations of the interferers 114, 125, information for identifying the audio signals made in the environment 108 by interferers 114, 125, information that identifies the first user 101, information that indicates what the users in the environment 108 are doing, information that indicates a type of environment 108, information that indicates the types of devices being used in the environment 108, any other type of information, or a combination thereof.

A noise profile may include, but is not limited to, audio information, signaling information, noise suppression algorithm information, noise cancellation information, or other information that corresponds to the noise conditions typically found in the environment 108. Similarly, there may be noise profiles corresponding to the interfering devices 115, 125, which may include audio information, signaling information, noise cancellation information, or other information specifically corresponding to the interfering devices 115, 125 and the noise conditions made by the interfering devices 115, 125. For example, for interfering device 115, there may be a noise profile that includes noise cancellation information and data corresponding to the audio interference signals outputted by the interfering device 115, the interferer's 114 pattern of usage as it relates to the interfering device 115, the type of the interfering device 115, any other information associated with the interfering device 115, or any combination thereof. Similarly, the interfering device 125, which in this case is a vehicle, may have its own noise profile, which includes similar types of information as stored for the interfering device 115, but which is tailored to the interfering device 125. Furthermore, the environment 108 itself may have its own noise profile, which includes similar information as stored for the interfering device 115, but which is tailored to the environment 108. For example, in FIG. 1, the environment 108 is a busy street, and the corresponding noise profile may include noise cancellation information and environmental characteristics that may be utilized in identifying and cancelling noises typically occurring on a busy street.

A user profile may be a profile corresponding to the first user 101 using the first user device 102, the interferer 114, the second user 110, or any other user. As an example, the user profile of the first user 101 may include audio information, such as, but not limited to, audio information identifying or otherwise associated with the voice of the first user 101. Additionally, the user profile may include other information associated with the first user 101, such as, but not limited to, a name of the first user 101, the age of the first user 101, demographic information associated with the first user 101, an acoustic dictionary corresponding to the first user 101, an ethnicity of the first user 101, the physical characteristics of the first user 101, and any other information. The user profile may also include information indicative of the voice characteristics of the first user 101, such as, but not limited to the accent information, tone information, pitch information, speech patterns, languages of the first user 101, or any other information associated with the speech of the first user 101. In addition to noise and user profiles, the system 100 may also include location profiles, which may include audio information, location information, noise cancellation information, or other information specific to a particular location, such as the environment 108.

Once the metadata, noise profiles, user profiles, location profiles, and other data are accessed by the system 100, the system 100, such as via the canceller 165, may utilize the metadata, noise profiles, user profiles, location profiles, and other data to effectively detect and separate each audio signal contained in the audio stream. In doing so, the system 100 may determine whether one or more interference signals exist in the audio stream in addition to the desired audio signal from the first user 101. If the system 100 determines that a portion of the audio stream correlates with metadata, profile, or other information identifying or otherwise corresponding to an interference signal, the system 100 may confirm that the portion of the audio stream is an interference signal that may be interfering with the first user's 101 desired audio signal. For example, one portion of the audio stream may correlate with interference signal information contained in a user profile associated with interferer 114, and another portion of the audio stream may correlate with an interference signal contained in a noise profile associated with the interferer 125.

After detecting an interference signal, the system 100 may then utilize the metadata, profiles, other data, or a combination thereof, to improve the efficiency and speed of noise suppression algorithms that may be utilized in cancelling the detected interference signals. For example, the canceller 165 may cancel any detected interference signals in the audio stream using the metadata, profiles, other data, and noise suppression algorithms. In certain embodiments, the canceller 165 may provide noise cancellation signals corresponding to the interference signals associated with interferers 114, 125, which may be utilized to cancel the interference signals from the audio stream to create a filtered audio stream. In certain embodiments, the interference signals may be cancelled or otherwise suppressed through the use of spatial filtering or other noise cancellation techniques.

Once the interference signals are cancelled from the audio stream, the system 100, such as via the canceller 165, may transmit the filtered audio stream to an intended destination. For example, the filtered audio stream may be transmitted to the second user device 111 so that the second user 110 may hear the desired audio signal from the first user 101 without having to experience interference from the interference signals in the original audio stream. The filtered audio stream may also be transmitted to the automatic speech recognition system 175 during the speech recognition session. In an illustrative example, the speech recognition session may be a session that the first user 101 is using to access various types of banking services. During such a session and prior to cancelling the interference signals, the automatic speech recognition functions of the automatic speech recognition system 175 may have difficulty capturing or processing the first user's voice inputs into an interface of the automatic speech recognition system 175 based on the noisy street environment 108 that the first user 101 is located in. However, once the filtered audio stream including the voice input speech of the first user 101 is transmitted to the automatic speech recognition system 175, the automatic speech recognition system's 175 ability to process the first user's 101 speech may be improved substantially. After the filtered audio stream is transmitted to the intended destination, the system 100 may include updating the metadata, the noise profiles, the user profiles, and other information in the system 100 based on the audio stream and based on the cancellation process itself. Notably, all of the operations of the processes described for the system 100 may be performed by utilizing cloud-computing network resources of the communications network 135.

In a second example scenario, as shown in FIG. 2, the first user 101 of the first user device 102 may be engaged in a communications session with the second user 110, who is using second user device 111. As in the previous example, the first user 101 may also be engaged in a speech recognition session with the automatic speech recognition system 175. In this example, an audio device 205 may be a potential interferer that may interfere with the communications of the first user 101. The audio device 205 may be a radio, a computer, a portable music player, or other audio device that may be configured to output music via one or more speakers 206 of the audio device 205. As the first user 101 speaks and prior to transmitting the speech to its intended destinations, the first user's 101 speech, along with any undesired background music outputted by the audio device 205 while the first user 101 is speaking, may be transmitted to the communications network 135 in an audio stream to be processed using the cloud-computing resources of the communications network 135.

Based on speech characteristics correlating to the first user 101 contained in a user profile of the first user 101 and based on harvested metadata associated with the first user 101, the canceller 165 may be able to determine which portion of the audio stream correlates to the speech of the first user 101. The user profile may be obtained from user database 156. Additionally, the canceller 165 may determine which portion of the audio stream correlates to the undesired background music outputted by the audio device 205. Furthermore, based on a music identifier 207 that identifies or matches information in the undesired music, the canceller 165 may determine which portion of the audio stream corresponds to the undesired music. The music identifier 207 may be stored and retrieved from the music database 157. Once the music is recognized and separated from the speech of the first user 101, the canceller 165 may cancel the music from the audio stream by utilizing the metadata and a noise profile including cancellation information for the music in conjunction with noise suppression algorithms, echo-cancellation techniques, and other similar cancellation procedures. In certain embodiments, the noise suppression may be performed solely by the canceller 165 and using cloud-computing resources, however, in other embodiments, the first user device 102 or other selected devices in the system 100 may assist in the cancellation process. Once the music is cancelled from the audio stream, the audio stream including the speech of the first user 101 may be transmitted to the second user device 111 of the second user 110 and to the automatic speech recognition system 175. Thus, the quality of the audio stream transmitted to the second user device 111 and to the automatic speech recognition system will be noticeably higher using the process described above.

In a third example scenario, as shown in FIG. 3, the first user 101 of the first user device 102 may be engaged in a communications session with the second user 110, who is using second user device 111. As in the previous example, the first user 101 may also be engaged in a speech recognition session with the automatic speech recognition system 175. In this example, an audio device 205 may be a potential interferer that broadcasts audio signals received from a broadcast device 305, such as a radio station or other similar device capable of transmitting broadcast data including, but not limited to, AM, FM, digital, satellite, or high definition radio. As the first user 101 speaks and prior to transmitting the speech to its intended destinations, the first user's 101 speech, along with any undesired broadcast audio outputted by the audio device 205 while the first user 101 is speaking, may be transmitted to the communications network 135 in an audio stream to be processed using the cloud-computing resources of the communications network 135.

In this example, the system 100 may have metadata, noise profiles, and other information corresponding to the broadcast audio signals transmitted from the broadcast device 305. The metadata, noise profiles, and other information may be utilized to recognize, in real-time, the broadcast audio signals in the audio stream. The broadcast device 305 and the broadcast signals may also be recognized based on a broadcast identifier 307 that contains information that matches information contained in the broadcast signals. In certain embodiments, the system 100 may be able to distinguish between broadcast signals received-over-the-air versus broadcast signals obtained via web-based sources, such as web feeds. Additionally, based on speech characteristics correlating to the first user 101 contained in a user profile of the first user 101 and based on harvested metadata associated with the first user 101, the system 100 may be able to determine which portion of the audio stream correlates to the speech of the first user 101. The canceller 165 may then cancel the undesired broadcast signals from the audio stream by utilizing the metadata and/or a noise profile including cancellation information for the broadcast signals in conjunction with noise suppression algorithms, echo-cancellation techniques, and other similar cancellation procedures. Once the broadcast signals are cancelled from the audio stream, the audio stream including the speech of the first user 101 may be transmitted to the second user device 111 of the second user 110 and to the automatic speech recognition system 175.

In a fourth example scenario, as shown in FIG. 4, the first user 101 of the first user device 102 may be engaged in a communications session with the second user 110, who is using second user device 111. As in the previous examples, the first user 101 may also be engaged in a speech recognition session with the automatic speech recognition system 175. In this example, television device 405 may be a potential interferer that outputs television audio signals associated with media programming playing on the television device 405. As the first user 101 speaks and prior to transmitting the speech to its intended destinations, the first user's 101 speech, along with any undesired television audio signals outputted by the television device 405 while the first user 101 is speaking, may be transmitted to the communications network 135 in an audio stream to be processed using the cloud-computing resources of the communications network 135.

In this example, the system 100 may have metadata, noise profiles, and other information corresponding to the television audio signals transmitted from the television device 405. The metadata, noise profiles, and other information may be utilized to recognize, in real-time or beforehand, the television audio signals contained in the audio stream. The television audio signals may be recognized beforehand, particularly when the media programming containing the television audio signals is controlled by the provider controlling the communications network 135. The television device 405 and the television signals may also be recognized based on a channel identifier 407 and media programming broadcast information 406 that contains information that matches at least a portion of the information contained in the television audio signals. Additionally, based on speech characteristics of the first user 101 contained in a user profile of the first user 101 and based on harvested metadata associated with the first user 101, the system 100 may be able to determine which portion of the audio stream correlates to the speech of the first user 101. The canceller 165 may then cancel the undesired television audio signals from the audio stream by utilizing the metadata and/or a noise profile including cancellation information for the television audio signals in conjunction with noise suppression algorithms, echo-cancellation techniques, and other similar cancellation procedures. Once the television audio signals are cancelled from the audio stream, the audio stream including the speech of the first user 101 may be transmitted via an acoustic transmission channel to the second user device 111 of the second user 110 and/or to the automatic speech recognition system 175.

In a fifth example scenario, as shown in FIG. 5, the first user 101 of the first user device 102 may be engaged in a communications session with the second user 110, who is using second user device 111. As in the previous examples, the first user 101 may also be engaged in a speech recognition session with the automatic speech recognition system 175. In this example, interferer 114 may be a potential interferer that is speaking aloud while using interfering device 115, and the interferer 114 may be located in the same environment 108 as the first user 101. As the first user 101 speaks and prior to transmitting the first user's 101 speech to its intended destinations, the first user's 101 speech, along with any speech of the interferer 114 and any audio signals outputted by the interfering device 115, may be transmitted to the communications network 135 in an audio stream to be processed using the cloud-computing resources of the communications network 135.

In this example, the system 100 may have metadata, noise profiles, and other information corresponding to the speech of the interferer 114 and the interfering device 115. This information may be obtained from the phone network 136, which may be the network that services both the first user's 101 phone calls and the interferer's 114 phone calls. The metadata, noise profiles, and other information may be utilized to recognize the speech of the interferer 114 and the audio signals outputted by the interfering device 115 contained in the audio stream. The interferer 114 may be recognized based on an interferer identifier 507 that contains information that matches information contained in the speech of the interferer 114, and/or based on a noise profile associated with the interferer 114. The audio signals outputted by the interfering device 115 may similarly be recognized based on a noise profile containing information correlating with the information contained in the audio signals outputted by the interfering device 115. Additionally, based on speech characteristics of the first user 101 contained in a user profile of the first user 101 and based on harvested metadata associated with the first user 101, the system 100 may be able to determine which portion of the audio stream corresponds to the speech of the first user 101. Notably, the first user's 101 information and the interferer's 114 information may be anonymized from each other or other systems using the cloud-computing resources of the communications network 135.

After detecting the speech of the interferer 114 and the interfering device 115 audio signals, the canceller 165 may then cancel the undesired speech of the interferer 114 and the interfering device 115 audio signals from the audio stream by utilizing the metadata and/or noise profiles including cancellation information for the speech and audio signals in conjunction with noise suppression algorithms, echo-cancellation techniques, and other similar cancellation procedures. Once the interferer's 114 speech and interfering device 115 audio signals are cancelled from the audio stream, the audio stream including the speech of the first user 101 may be transmitted via an acoustic transmission channel to the second user device 111 of the second user 110 and/or to the automatic speech recognition system 175. Notably, metadata and user profiles for the first user 101, the interferer 114, and the interfering device 115 may be updated based on the audio stream and based on the cancellation process.

In a sixth example scenario, the first user 101 of the first user device 102 may be engaged in a communications session with the second user 110, who is using second user device 111. As in the previous examples, the first user 101 may also be engaged in a speech recognition session with the automatic speech recognition system 175. In this example, a local noise source 605, located in the same environment 108 as the first user 101, may be generating interfering audio signals that may potentially interfere with the first user's 101 communications. As the first user 101 speaks and prior to transmitting the first user's 101 speech to its intended destinations, the first user's 101 speech, along with the interfering audio signals outputted by the local noise source 605, may be transmitted to the communications network 135 in an audio stream to be processed using the cloud-computing resources of the communications network 135.

In this example, the system 100 may have metadata, noise profiles, and other information corresponding to the interfering signals outputted by the local noise source 605. The metadata, noise profiles, and other information may be utilized to recognize, in real-time or beforehand, the interfering signals contained in the audio stream. The interfering signals and local noise source 605 may also be recognized based on an interferer identifier 607 and location information 606 that contains information that matches information contained in the interfering audio signals and information associated with the local noise source 605. Additionally, based on speech characteristics of the first user 101 contained in a user profile of the first user 101 and based on harvested metadata associated with the first user 101, the system 100 may be able to determine which portion of the audio stream corresponds to the speech of the first user 101. The canceller 165 may then cancel the undesired interference signals from the audio stream by utilizing the metadata and/or a noise profile including cancellation information for the interference signals in conjunction with noise suppression algorithms, echo-cancellation techniques, and other similar cancellation procedures. Once the interference signals from the local noise source 605 are cancelled from the audio stream, the audio stream including the speech of the first user 101 may be transmitted via an acoustic transmission channel to the second user device 111 of the second user 110 and/or to the automatic speech recognition system 175.

Notably, as shown in FIG. 1, the system 100 may perform any of the operative functions disclosed herein by utilizing the processing capabilities of server 160, the storage capacity of the databases 155, 156, 157, or any other component of the system 100 to perform the operative functions disclosed herein. The server 160 may include one or more processors 162 that may be configured to process any of the various functions of the system 100. The processors 162 may be software, hardware, or a combination of hardware and software. Additionally, the server 160 may also include a memory 161, which stores instructions that the processors 162 may execute to perform various operations of the system 100. For example, the server 160 may assist in processing loads handled by the various devices in the system 100, such as, but not limited to, receiving the audio streams associated with the first and second users 101, 110, determining if the audio stream includes an interference signal, analyzing the audio streams based on metadata, cancelling the interference signals, transmitting the audio streams after performing the cancellation of the interference signals, determining the environment 108 of the first and second users 101, 110, obtaining usage patterns for the first and second users 101, 110, obtaining sensor data, identifying acoustic parameters based on the sensor data, and performing any other suitable operations conducted in the system 100 or otherwise. In one embodiment, multiple servers 160 may be utilized to process the functions of the system 100. The server 160 and other devices in the system 100, may utilize the databases 155, 156, 157 for storing data about the devices in the system 100 or any other information that is associated with the system 100. In one embodiment, multiple databases 155, 156, 157 may be utilized to store data in the system 100.

Although FIGS. 1-6 illustrate specific example configurations of the various components of the system 100, the system 100 may include any configuration of the components, which may include using a greater or lesser number of the components. For example, the system 100 is illustratively shown as including a first user device 102, a second user device 111, a interferer 114, an interfering device 115 a interferer 125, communications network 135, a phone network 136, a server 140, a server 145, a server 150, a server 160, a database 155, a user database 156, a music database 157, a canceller 165, an automatic speech recognition system 175, an audio device 205, a broadcasting device 305, a television device 405, and a local noise source 605. However, the system 100 may include multiple first user devices 102, multiple second user devices 111, multiple interferers 114, 125, multiple interfering devices 115, multiple communications networks 135, multiple phone networks 136, multiple servers 140, 145, 150, and 160, multiple databases 155, 156, 157, multiple cancellers 165, multiple automatic speech recognition systems 175, multiple audio devices 205, multiple broadcasting devices 305, multiple television devices 405, multiple local noise sources 605, or any number of any of the other components in the system 100. Furthermore, in certain embodiments, substantial portions of the functionality and operations of the system 100 may be performed by other networks and systems that may be connected to system 100.

As shown in FIG. 7, an exemplary method 700 for providing cloud acoustic enhancement is schematically illustrated, and may include, at step 702, receiving an audio stream including a desired audio signal associated with a user, such as first user 101. For example, the audio stream may be a voice communication, a music communication, or any other type of audio communication received from first user 101 via the first user device 102. The communication may be intended to be sent to the second user device 111 of the second user 110, to the automatic speech recognition system 175, to any other desired destination, or any combination thereof. In certain embodiments, the receiving of the audio stream may be performed by the canceller 165, the servers 140, 145, 150, 160, the databases 155, 156, 157, any combination thereof, or by any other appropriate device. Once the audio stream is received, the method 700 may include, at step 704, accessing metadata, user profiles, noise profiles, sensor, data, or any other information to assist in determining if interference signals also exist in the received audio stream. In certain embodiments, the metadata, user profiles, noise profiles, sensor data, or any other information may be accessed from database 155, user database 156, music database 157, any combination thereof, or by any other appropriate device. In addition to accessing the metadata, profiles, and data, from databases 155, 156, 157, additional metadata and data may be harvested in real-time from any of the devices in the system or from any of the signals traversing the system 100.

After accessing and harvesting the metadata, user profiles, noise profiles, sensor, data, or any other information, the method 700 may include, at step 706, determining whether the audio stream includes an interference signal. The audio stream may be determined to include an interference signal if a portion of the audio stream correlates with the metadata, user profiles, noise profiles, sensor data, or any other information that identifies the interference signal as such. In certain embodiments, the determination as to whether the audio stream includes the interference signal may be performed by the canceller 165, the first user device 102, the servers 140, 145, 150, 160, any combination thereof, or by any other appropriate device. If the audio stream is determined to not include an interference signal, the method 700 may include, at step 708, transmitting the audio stream directly to the intended destination. For example, if the intended destination is the second user device 111 or the automatic speech recognition system 175, the audio stream may be directly sent to such destinations. In certain embodiments, the audio stream may be transmitted by utilizing the canceller 165, the first user device 102, the servers 140, 145, 150, 160, any combination thereof, or by any other appropriate device.

If, however, the audio stream is determined to include the interference signal, the method 700 may include, at step 710, cancelling, or otherwise suppressing, the interference signal from the audio stream. The interference signal may be cancelled by utilizing the cloud-computing resources of the communications network 135, the metadata, the user profiles, the noise profiles, the sensor data, or any other information in conjunction with noise suppression and cancellation algorithms and techniques. In certain embodiments, the interference signal may be canceled by utilizing the canceller 165, the first user device 102, the servers 140, 145, 150, 160, any combination thereof, or by any other appropriate device. Once the interference signal is cancelled or otherwise suppressed, the method 700 may include, at step 712, transmitting the audio stream including the desired audio signal associated with the user to an intended destination. The audio stream, for example, may be transmitted to the second user device 111, the automatic speech recognition system 175, or to any other intended destination. In certain embodiments, the audio stream may be transmitted by utilizing the canceller 165, the first user device 102, the servers 140, 145, 150, 160, any combination thereof, or by any other appropriate device.

At step 714, the method 700 may include updating the metadata, the noise profiles, the user profiles, the sensor data, or any other information based on the audio stream, based on the cancellation process, based on the devices in the system 100, or any combination thereof. It is important to note that the methods described above may incorporate any of the functionality, devices, and/or features of the system 100 and subsystems described above, or otherwise, and are not intended to be limited to the description or examples provided herein.

Notably, the system 100 and methods disclosed herein may include additional functionality and features. In certain embodiments, the visual, audio, and other information may be obtained by utilizing any type of sensor, such as, but not limited to, any visual sensor, any acoustic sensor, any recording device, any light sensor, any other type of sensor, or a combination thereof. Additionally, information and metadata may be obtained by using visual information captured by the camera 105, acceleration data captured by the accelerometer 106, orientation data captured using the gyroscope 109, and location data captured by the global positioning sensor 107. Supplemental information from such sensors may be utilized to identify or refine, locally or in concert with cloud-based network resources, acoustic parameters that may be useful in subsequent processing of the audio streams. For example, the orientation of the first user device 102 may be obtained from metadata obtained from the accelerometer 106. As an example, the orientation and placement of the first user device 102 on a surface may potentially impact the acoustic performance of the first user device 102 in predictable ways, and may assist in subsequent processing of audio streams associated with the first user device 102.

In certain embodiments, the cloud-computing resources of the communications network 135 may be utilized to collect and gather historical usage patterns associated with the first user 101, the second user 110, the interferer 114, or other users to augment the noise cancellation process. For example, if the first user 101 commutes daily by car while listening to a selected radio station, this information may be transmitted into the communications network 135 so as to enhance the responses time and performance of noise cancellation processing when the first user 101 takes calls from his car.

Similarly, historical data about the acoustic environments 108 that the first user 101 is located in, such as a night club or an outdoors area, may be utilized to enhance the performance of the noise cancellation process. The noise profiles of such environments 108 may be radically different from one another, and identifying them may assist in mitigating the deleterious effects of background noise on automatic speech recognition performance or various types of communications sessions. Additionally, in certain embodiments, using the system 100 to determine whether the first user 101 is positioned in a moving vehicle, such as a bike, car, airplane, or train, may assist in mitigating the effects of interference. Each mode of transportation may have a corresponding noise profile, and, as a result, some of the interference signals associated with such modes of transportation may be predictable. Therefore, such information may be helpful in cancelling noises associated with such modes of transportation.

Referring now also to FIG. 8, at least a portion of the methodologies and techniques described with respect to the exemplary embodiments of the system 100 can incorporate a machine, such as, but not limited to, computer system 800, or other computing device within which a set of instructions, when executed, may cause the machine to perform any one or more of the methodologies or functions discussed above.

The machine may be connected with any component in the system 100. In a networked deployment, the machine may operate in the capacity of a server or a client user machine in a server-client user network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may comprise a server computer, a client user computer, a personal computer (PC), a tablet PC, a laptop computer, a desktop computer, a control system, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine.
